Laymans terms

This code means that the car's computer noticed a problem with the signals from the parts that tell how much you're pressing the gas pedal. It's like when two friends tell you different stories about the same event, and you get confused.

Explanation

The engine control module (ECM) has detected a discrepancy between the voltage signals from the throttle position sensor A and the pedal position sensor G.

Technical description

The P2AD3 code indicates that the ECM has found a voltage correlation issue between the throttle position sensor A and the pedal position sensor G. These sensors are responsible for communicating the position of the throttle and pedal to the ECM. If the signals from these sensors do not match the expected values, the ECM triggers this code.

Symptoms

• Check Engine Light illuminated

• Poor acceleration

• Unstable idle

Common Causes

• Faulty throttle position sensor

• Faulty pedal position sensor

• Wiring issues or poor connections
